Comment 1 Fabian Deutsch 2012-09-23 18:50:16 UTC

kernel-3.3.4-5.fc17.x86_64 works better.

Comment 2 Fabian Deutsch 2012-09-24 14:48:18 UTC

Can you elaborate why this has been closed?

Comment 3 Justin M. Forbes 2012-09-24 14:51:38 UTC

Sorry, read that as 3.5.4 (the current update) not 3.3.4 working better. In the meantime, would you mind testing with 3.5.4?

Comment 4 Fabian Deutsch 2012-09-24 14:55:46 UTC

Yep, will test it. Thanks.

Comment 5 Fabian Deutsch 2012-09-24 15:13:54 UTC

The kernel module in use is r8712u

3.5.4 has the same issues as 3.5.3. So not working well.

Comment 7 Josh Boyer 2013-01-02 17:39:09 UTC

Are you still seeing this with the 3.6.11 or newer kernel updates?

Comment 8 Larry Finger 2013-01-02 17:49:49 UTC

In addition, please post the md5sum for file /lib/firmware/rtlwifi/rtl8712u.bin.

Comment 9 Josh Boyer 2013-03-12 20:24:52 UTC

Closing this out due to lack of response.  If you're still seeing this with 3.7.9 or 3.8.2, please let us know and answer Larry's question in comment #8.

Comment 10 Fabian Deutsch 2013-03-12 20:57:24 UTC

I didn't note that input was needed - darn. Now testing the reliability.

$ md5sum /lib/firmware/rtlwifi/rtl8712u.bin
200fd952db3cc9259b1fd05e3e51966f  /lib/firmware/rtlwifi/rtl8712u.bin

Comment 11 Fabian Deutsch 2013-03-12 21:06:42 UTC

And it seems to be more reliable compared to before.
I shove some data over the wireless link and it didn't break down.

Comment 12 Larry Finger 2013-03-12 21:34:43 UTC

That is the correct firmware (finally).

Comment 13 Fabian Deutsch 2013-03-13 07:49:30 UTC

> That is the correct firmware (finally).

So the problem was an incorrect firmware?

Comment 14 Larry Finger 2013-03-13 14:51:15 UTC

For a time, the official firmware repositories included a firmware version that failed on some devices. Unfortunately, my device did not fail, thus the problem did not show up in my testing.

Your problem may have been faulty firmware, but we will likely never know. As the result of testing on another b.r.c report, we identified the problem and Fedora reverted the firmware version. The faulty firmware was included in the linux-firmware repo in July 2012 and reverted in September 2012.

Comment 15 Fabian Deutsch 2013-03-13 15:03:32 UTC

Right, thanks for that explanation!

And have a nice day :)
